We highlight near–real-time forest monitoring technologies that provide alerts of forest loss at relevant spatial and temporal scales to prevent further erosion. Doubling the tiger population by 2022 requires moving beyond tracking annual changes in habitat. Habitat loss in source population sites within 76 landscapes ranged from no loss to 435 ± 124 km 2 ( x ¯ = 24 km 2, SD = 89, total = 1676 ± 476 km 2).
Habitat loss was unevenly distributed within a subset of 29 landscapes deemed most critical for doubling wild tiger populations: 19 showed little change (1.5%), whereas 10 accounted for more than 98% (57,392 ± 16,316 km 2) of habitat loss. Across the 76 landscapes, forest loss was far less than anticipated (79,597 ± 22,629 km 2, 7.7% of remaining habitat) over the 14-year study period (2001–2014).

Our analysis provides an update of the status of tiger habitat and describes new applications of technology to detect precisely where forest loss is occurring in order to curb future habitat loss. Using a new satellite-based monitoring system, we analyzed 14 years of forest loss data within the 76 landscapes (ranging from 278 to 269,983 km 2) that have been prioritized for conservation of wild tigers. Habitat loss, along with poaching, can undermine the international target recovery of doubling the number of wild tigers by 2022.
The global population of wild tigers remains dangerously low at fewer than 3500 individuals.
